Definitions
- the microprocessor 200 starts a converter cycle by placing a command on data bus 214 to select the channel, and driving lead 218 low.
- Lead 218 is connected to one input of two NANDs 320 and 322.
- the second input of NAND 320 is connected to +5V and the output of the NAND is connected to a further NAND 324.
- the E output of microprocessor 200 is connected to one input of NANDs 322 and 324 and the outputs of these NANDs are connected to the R ⁇ and WR ⁇ inputs, respectively, of the converter.
- NAND 324 produces a low output when the clocking signal on lead 222 goes high.
- the output of NAND 324 enables the converter so that the operation specified by the command is carried out.
- M1IN is then sent to VIA 208 and the VIA produces a PWM output signal with a 60 % duty cycle over its bus to energise Mosfets 290, 295 thereby energising motor M1 in a sense which moves end A ( Figure 2) of the shearbar 102 toward the cutterhead 100.
- step 1212 the motor current value obtained during the last execution of the NMIR routine is compared to a value representing the maximum allowable current. If the motor current does not exceed the maximum allowable value then at step 1215 it is compared with a value representing the minimum allowable current. It may be noted that steps 1213-1222 of the ADJUST routine correspond exactly with steps 1107-1113, 1120-1122 and 1130-1132 of the PULOUT subroutine described above, except that an excessive current during a long interval sets an EOTIN flag instead of an EOTOUT flag.
- the program sets flags to turn on one of the indicators 314 to indicate EOT and sound an alarm, and then jumps to the ALARM routine.
- the programs sets appropriate flags to turn on the RPM indicator and the alarm, and jumps to the ALARM routine.
- the RPMOK flag is tested prior to any motor actuation. If the flag is not set the program sets flags for giving the alarm indication at step 1281 tests the QUIT flag to see if the operator has depressed the QUIT switch. If he has, the program jumps to the READY routine. If he has not, a Wait for Interrupt is executed during the wait. The program then branches back to step 1202 to again check the RPMOK flag. If the cutterhead 100 is up to speed the program then clears the alarm flags at step 1203.
